The Correct Option is A
Solution and Explanation
Refrigerants are given standard numbers for easy identification.
Ammonia is a widely used natural refrigerant in industrial refrigeration systems like cold storages and ice plants.
In refrigerant numbering, ammonia is designated as R-717.
R-134 (R-134a) is tetrafluoroethane, used in domestic refrigerators and car ACs.
R-718 refers to water used as a refrigerant in special applications.
R-152 (R-152a) is difluoroethane, used as a low pressure refrigerant.
Therefore, ammonia is correctly identified as R-717.
